ISSUE-42: Align ssn to to implement best practices as defined in our bp deliverable.

<trackbot> Notes added to ISSUE-42 Align ssn to to implement best practices as defined in our bp deliverable..

Armin, this issue might not make much different in the ontology

<ahaller2> http://w3c.github.io/dwbp/usecasesv1.html

<ahaller2> http://w3c.github.io/dwbp/bp.html

Simon, there is no relevant properties to Spatial elements

<ahaller2> https://www.w3.org/TR/dwbp/

<mlefranc> http://w3c.github.io/sdw/bp/?

<ahaller2> https://www.w3.org/TR/sdw-bp/

<SimonCox> http://w3c.github.io/sdw/bp/

<mlefranc> ack

<mlefranc> s-

mlefranc: we might put a note how to annotating spatial properties to System

<mlefranc> DanhLePhuoc: hasLocation in Dolce -> people in previous SSN used it a lot,

<ahaller2> DanhLePhuoc: Sensors have locations, which is a popular property

<mlefranc> ... FeatureOfInterest may be spatial things

<mlefranc> ... location of the sensor when it's moving ?

<mlefranc> ... something in the document that links to the BP for that ?

<SimonCox> Moving sensors is a common requirement. Probably the best work in the Sensor/Observation space would be from the Oceans community

<SimonCox> also Meteorology.

<SimonCox> They have ships, balloons, soundings.

<SimonCox> Jeremy Tandy knows about this.

KJanowic: we can't have assumption on hasLocation, that might break our current axioms

<SimonCox> FeatureOfInterest models usually come from domains ... though it would be nice to have some generic patterns

<mlefranc> sentence that says: instances of Sensors, Actuators, Samplers, Systems, and FeatuteOfInterset MAY also be instances be SpatialThing s ?

<KJanowic> FOI, Samplers, Actuators, Sensors, Platforms and so on

<KJanowic> I can do so

KJanowic: we should out a note how to model spatial aspect to geospatial...

<KJanowic> I can write

<KJanowic> simon edit

simon: we need acknowledge a need, so, propose a solution, pointers to the potential solutions

<ahaller2> http://w3c.github.io/sdw/ssn/#TheSSNontology

simon: we need to make a careful one

ahaller2: KJanowic volunteer to put the note

<KJanowic> descriptions can be normative

<KJanowic> ahaller2: can you asign me an action?

<ahaller2> ACTION: KJanowic to write a short piece on locations and moving sensors, SimonCox to double-check [recorded in http://www.w3.org/2017/04/12-sdwssn-minutes.html#action01]

<trackbot> Created ACTION-311 - Write a short piece on locations and moving sensors, simoncox to double-check [on Krzysztof Janowicz - due 2017-04-19].

KJanowic: how should we coordinate the editing to avoid conflicts

ahaller2: we will stop to use specgen as it takes more effort than doing that manually
... the tool does not generate some classes and properties

<mlefranc> https://ns.inria.fr/sparql-template/

<KJanowic> I think you can use html, just use seperate files instead of everybody working on the main document.

<KJanowic> Exactly

DanhLePhuoc: we will the same style of OBE alignment proposed by SimonCox for other alignments

<ahaller2> close issue-42

<trackbot> Closed issue-42.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/44

ahaller2: there is section in the document addressing that

<ahaller2> http://w3c.github.io/sdw/ssn/#Developments

<KJanowic> (afk for 2min)

ahaller2: we just need to extend this section a bit to fully address this issue
... suggest to close the issue or whoever will write this section will close it

<ahaller2> https://www.w3.org/2015/spatial/track/issues/47

ahaller2: i have done that for SOSa
... I can close when i'm doing it

<ahaller2> https://www.w3.org/2015/spatial/track/issues/44 to be closed by KJanowic once done

<ahaller2> https://www.w3.org/2015/spatial/track/issues/47 to be closed by ahaller2 once done in document

<ahaller2> https://www.w3.org/2015/spatial/track/issues/50

<KJanowic> (back)

https://www.w3.org/2015/spatial/track/issues/50 to be closed by DanhLePhuoc when Danh finish this section

<ahaller2> https://www.w3.org/2015/spatial/track/issues/50 to be closed by DanhLePhuoc once done in WD

<ahaller2> https://www.w3.org/2015/spatial/track/issues/52

<KJanowic> Sure, I will do so

<ahaller2> close issue-52

<trackbot> Closed issue-52.

adrmin: we have done a lot of work on this, so, we can close it

<ahaller2> https://www.w3.org/2015/spatial/track/issues/53

ahaller2: this can be a future work

simon: this wouldn't be that hard

ahaller2: it can go the non-normative part

KJanowic: we can put a note as the future work

<ahaller2> close issue-53

<trackbot> Closed issue-53.

<ahaller2> ACTION: ahaller2 to ask if non-normative alignments can be added to the document after last call (e.g. PROV-O alignment) [recorded in http://www.w3.org/2017/04/12-sdwssn-minutes.html#action02]

<trackbot> Created ACTION-312 - Ask if non-normative alignments can be added to the document after last call (e.g. prov-o alignment) [on Armin Haller - due 2017-04-19].

<ahaller2> https://www.w3.org/2015/spatial/track/issues/54

<ahaller2> close issue-54

<trackbot> Closed issue-54.

<ahaller2> out of scope as issue-53 is future work

<ahaller2> https://www.w3.org/2015/spatial/track/issues/55

<mlefranc> For your interest, I keep track of the resolutions and will update the wiki page with those

<KJanowic> Thanks Maxime

<KJanowic> 55 is out of scope

<KJanowic> we already align to o7M etc

ahaller2: it is interesting but it should be marked a future work

<ahaller2> close issue-55

<trackbot> Closed issue-55.

<KJanowic> I have to teach now, sorry. good luck guys and thanks for all your hard work

<ahaller2> https://www.w3.org/2015/spatial/track/issues/56

this issue does not have another with it

DanhLePhuoc: TD is still an on-going work, so, we don't have to align to them

mlefranc: just put a note to hint how TD can be aligned with SOSA/SSN

<mlefranc> an instance of a platform may be an iot device

<ahaller2> ACTION: ahaller2 to look into WoT device and potentially add an rdfs:comment or skos:example where appropriate (Platform class?) [recorded in http://www.w3.org/2017/04/12-sdwssn-minutes.html#action03]

<trackbot> Created ACTION-313 - Look into wot device and potentially add an rdfs:comment or skos:example where appropriate (platform class?) [on Armin Haller - due 2017-04-19].

<ahaller2> close issue-56

<trackbot> Closed issue-56.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/57

there is no ontology in coverage deliverable so, we can close this issue

<ahaller2> close issue-57

<trackbot> Closed issue-57.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/58

ahaller2: it's not required to cover all the requirements, we may include in here and there in the document
... editors should have check the UCR again to cover it in the document when it's relevant

<ahaller2> close issue-58

<trackbot> Closed issue-58.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/59

<ahaller2> https://www.w3.org/2015/spatial/wiki/SSN_Wish_List

<SimonCox> Umbrella issue - for some elements new specific issues were created; if no new issue, won't get to it now. Close issue 59

<ahaller2> close issue-59

<trackbot> Closed issue-59.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/60

ahaller2: Armin volunteer to do the German and Raul proposed to do in Spanish
... I will check again if we can do it during the public review

<mlefranc> Antoine Zimmermann and myself will do the French one

<ahaller2> ACTION: mlefranc and antoine to write French labels and comments in SOSA and SSN [recorded in http://www.w3.org/2017/04/12-sdwssn-minutes.html#action04]

<trackbot> Created ACTION-314 - And antoine to write french labels and comments in sosa and ssn [on Maxime Lefrançois - due 2017-04-19].

<ahaller2> close issue-60

<ahaller2> close issue-61

<trackbot> Closed issue-61.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/71

<SimonCox> Use temporal primitives from OWL-Time (not SAO Time)

<SimonCox> In OGC standard TimeSeriesML a temporal 'coverage' is embedded in the Observation/result

time series and modelling sensor data as stream data is out the scope

<ahaller2> close issue-71

<trackbot> Closed issue-71.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/72

<SimonCox> There are many options for time-series - not clear that SAO is better than any of the others

<ahaller2> ACTION: DanhLePhuoc to check if what we use is actually called RDF(S)++, RDF(S) plus inverseOf [recorded in http://www.w3.org/2017/04/12-sdwssn-minutes.html#action05]

<trackbot> Error finding 'DanhLePhuoc'. You can review and register nicknames at <http://www.w3.org/2015/spatial/track/users>.

<ahaller2> close issue-72

<trackbot> Closed issue-72.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/84 and https://www.w3.org/2015/spatial/track/issues/102

ahaller2: there are several discussions on these issues with a lot emails

<mlefranc> Thread Voting on a name for ssn this week in plenary ?

<mlefranc> https://lists.w3.org/Archives/Public/public-sdw-wg/2017Apr/0076.html

<mlefranc> https://lists.w3.org/Archives/Public/public-sdw-wg/2017Apr/0014.html

<mlefranc> --> start of the thread

most of the options proposed have some objections, so, we stick the the current naming scheme

we haven't been able to reach the agreement on a common name space prefix, so, the fall back solution is now using SOSA and SSN, the status quo

<mlefranc> https://www.w3.org/2017/Process-20170301/#WGChairReopen

<ahaller2> https://www.w3.org/2017/03/21-sdw-minutes

<mlefranc> We reopen the decision made during F2F in Delft, because some people that were not able to attend the scheduled meeting had new information about this.

<mlefranc> then we can vote on using two prefixes and two namespaces

<ahaller2> Objections to the decision were made by several people as of https://lists.w3.org/Archives/Public/public-sdw-wg/2017Apr/0014.html

<ahaller2> Objections were made to the resolution: That the 'two' ontologies share a common name with either prefix or suffix to distinguish, e.g. 'lite' or 'full'

<ahaller2> PROPOSED: That the two ontologies use seperate prefixes as of the status quo, i.e. SOSA and SSN

<ahaller2> +1

+1

<mlefranc> 0

<SimonCox> +1

RESOLUTION: That the two ontologies use seperate prefixes as of the status quo, i.e. SOSA and SSN

<trackbot> Closed issue-84.

<ahaller2> close issue-102

<trackbot> Closed issue-102.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/103

we will use the similar style of OBE alignment

<ahaller2> close issue-103

<trackbot> Closed issue-103.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/81

<SimonCox> Alignment graphs should import the two ontologies that they align

<ahaller2> close issue-83

<trackbot> Closed issue-83.

<ahaller2> https://www.w3.org/2015/spatial/track/issues/93

<SimonCox> Rewording of definition in SOSA was deliberate

<SimonCox> broader scope than SSN, so description should *not* be the same

<ahaller2> New sensor comment: Device, agent (including humans), or software (simulation) involved in, or implementing, a Procedure. Sensors respond to a stimulus, e.g., a change in the environment, or input data composed from the results of prior Observations, and generate a Result. Sensors can be mounted on Platforms.

<SimonCox> includes software, people (interpretations) as well as classic sensors
